DRAFT-EQUALIZER.

' Specification of Letters Patent.

. Patented Nov. 13, 1906.

Application filed July 13, 1905. Serial No. 269,532.

. 'IIDPI'OVG the construction of draft-equalizers and to provide aslmple, inexpensive, and eflicient one of great strength and durabilitydesigned particularly for use on cultivators' and adapted to equalizethe draft between three horses.

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfullydescribed, illustrated in the accompanyingdrawings, and pointed outin the claims hereto appended, it being understood that various changesin the form, pro-1 portion,- size, and minor details of constructionwithin the scope of the claims may be resorted to without departing fromthe spiritl or sacrificing any of the advantages ofthe in-- vention.

In the drawings, Figure 1 is a plan view of a draft-equalizerconstructed in accordance with this invention. Fig. 2 is a frontelevation of the same, the draft beams or tongues being in section. Fig.3 is a vertical sectional view taken substantially on the line 3 3 ofFig. 1. Fig. 4 is a similar view taken substantially on the line 4 4 ofFig. 1.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates an axletree forming a portion of the frame of a cultivatorand secured to the rear portion of a pair of longitudinal draft beams ortongues 2, which are connected in advance of the axletree by means of atransverse bar 3, preferably constructed of flanged metal, such asangle-iron, as clearly shown in Figs. 3 and 4 of the drawings. Thetransverse bar, which extends laterally from the draft beams or tongues,forms a support from which is hung central and side upright oscillatorylevers 4 and 5, fulcrumed at their upper ends and having their lowerends carrying swingletrees 6 and 7. The upright oscillatory levers areforked and are pivoted to the transverse bar by means of brackets orhangers 8 and 9, having horibrace.

zontal pivots or pintles, which are arranged in perforations of thelevers 4 and 5. The sides 10 of the fork of the central lever 4 divergeand are inclined, as shown, and the horizontal pintles or pivots extendinto perforations or openings of the sides 10 from the outer faces ofthe latter, whereby the central lever will be securely retained inposition when the brackets or hangers 8 are secured to the transversebar 3. The outer side of the fork of the outer levers is vertical andforms a continuation of and is arranged in the same plane as the lowerportion of the outer levers. The inner side 11 .of the fork of the outerlevers is inclined and forms a the end brackets 9 are shown extendinginto the openings of the outer'levers from the inner side of the same,and'keys 12 or other suitable fastening devices may be provided Thehorizontal pivots or pintles of for retaining thelevers onthe pivots or.

pintles; but the brackets at the outer levers may be arranged like thoseof the central bracket. employed for hinging the upper ends of thelevers to the supporting transverse bar. The whiffletrees 6 and 7 arepivotallyconnected with the lower ends of the upright levers by means oflinks 13, which may be of any desired construction. 13i

Any other suitablemeans may be.

n f The central and side levers 4 and 5 are coni nected with a pair oftransversely-disposed approximately horizontally arranged equalizingbars or levers 14, connected between their ends by links 15 with anaxletree, preferably at the upper face thereof. 15 are pivoted at theirrear ends to the axletree by means of bolts or other suitable fasteningdevices, and their front ends 16 are forked or bifurcated to receive thedraftequalizing bars or levers, to which they are pivoted. The innerarms of the draft-eqaulizing bars or levers, which are twice the lengthof the outerarms, are connected with the central upright leve'r, whichis provided at an intermediate point with'an inwardlyextending bracket17, having a forked or bifurcated portion, in which is mounted a groovedpulley or wheel 18. The grooved pulley or wheel 18 receives a chain 19or other suitable flexible connection, which has its terminals connectedwith the inner ends of the equalizing bars or levers by means of links20. The links 20 consist of short rods provided at their terminals witheyes, the rear eyes being linked into eyebolts 21 and ed to move on'thepulley,

with the upright the front eyes being linked into the endsv of the chain19. The eyebolts pierce the inner ends of the equalizing bars or leversand are provided with nuts, as shown. The outer ends of the equalizingbars or levers are provided with eyebolts 22 and are connected with theouter upright levers 5 by means of rods or links 23, which form stiffconnections between the outer upright levers and the equali'zmg bars orlevers. The links or'ro'ds' 23 are provided at their rear end with eyesto receive the eyebolts 22, and the front ends of thesaid links or rods23 are pivoted to the lower ends of the outer u right levers,-as clearlyindicated in Fig. .3 o the drawings.

The equalizing bars or leversare connected levers, and they are adaptedto oscillate to equalize the draft between three draft-animals, and whenthe levers 1 4 oscillate the flexible connection 19 is adaptand theupright levers 4 and .5 are also adapted to oscillate toyield to themovement of the equalizing bars or levers.

The device is designed particularly for use on cultivators and, asshown, is adapted to equalize the draft between three horses or otherdraft-animals; but by substituting doubletrees for thesw-ingletrees thedevice may be advantageously employed for equalizing the *draft betweensiX horses. The equalizer may, however, be advantageously employedonma-chines other thancultival tors.

Having thus fully described my invention, what'lclaim as new, and desireto secure by Letters Patent, is-

1. The combination with a frame, ofa pair of transversely-disposedhorizontally-swing ingequalizing-bars or levers fulcrumed at anintermediate point on the said frame to form inner and outer arms,central and outer upright levers depending from the frame, means forconnecting the outer upright levers with l the outer arms of thehorizontally-swinging equalizing bars or levers, a flexible. connectionslidable on the central upright lever and i connected with the innerarms of the said equalizing bars or levers, and whiflletrees connectedwith the outer and central upright levers.

2. In a device of the class described, the combination with a frame, ofa pair of transl versely-disposed horizont ally-swinging equalizing bars.or=levers fulcrumed atan'intermediate point on the said frame to forminnerand outeriarms, upright central and outer levers depending from theframe, means for 1 connecting the outer arms of the equalizing bars orlovers with the lowerends of the outer upright levers, a flexibleconnection slidably connected with the central upright lever at a pointbetween the ends thereof, said flexible l connectionhaving its terminalsconnected with the inner arms of the saidequalizing 'bars or levers, andwvhiffletrees connected with the upright central and outer levers.

Ina device of the class described,-the combination of central and outerupright levers having forked upper portions forming braces, whiifletreesconnected with the lower ortions of the levers, and equalizing bars or vevers connected with the said levers. 1 testimony thatl claim theforegoing as my own I havehereto a'ffiXed mysignature in the presence oftwo. witnesses.
